Abstract (en)
The invention describes a device for controlling the diameter of cylindrical sections of a rotating calender roll. The device comprises at least one nozzle which direct a jet of air against the calender roll. The flow of air from each nozzle remains approximately constant. Only the temperature of the jets change as heating elements associated with each nozzle are energized or deenergized. Thermal expansion or contraction, resulting from localized heating or cooling by the air jets, corrects local non-uniformities in the calender roll diameter.
